Textile-machines of-thegeferred to type wind 6 the yarn on tubularspools, or cylinders, while a simultaneously impartingto the yarn apredetermined twist. When such machines apply the yarn to the cylindersin progressively shortened I "yarn layers so as to effect inwardlyinclined, or 1 uniforml tapered yarn package ends, the yarn.

during winding, has a tendenc to more or less frequently drop off atsaid inclined ends. The dropped portion of the yarnuis referred to inthe trade. as a cross-over," and is detrimental for various reasons..For example, the -accompany-' ing yarn slackeningand Jerking actionusually causes. rupture of the yarn. Rectification of this diilicultinvolves machine, production losses,

' yarn wastage and labor costs; The responsibility for such losses anddiillculties is mainly attributable to the yarn feeding means of suchgig.- chines and the inability of such means to effectively andefllciently perform its intended function under various operating.conditions and 25 speeds.

. it One object of my. invention isto provide a novel textile machine ofthe referred to'type which eliminates the mentioned and other losses'and diillculties. v I

Another object is to. provide such a machine having novel yarn feedingmeans. i

Another object is to provide such a machine comprising a reciprocallyoperated yarn feeding matically adjusted in. correspondence with thechange in location of the yarn receiving surface of the device on whichthe yarn i wound, so thatv said element and surface. will remainindeterminedly fixed positional relationship throughout 9 the entire yarnwinding'proce e.

It is also an obiect to provide such a machine having novel means forprogressively varying the i 1 stroke of'said yarn feeding element,

An additional "object is to provide such a ma-; chine in which thestrokeoi sald elment is determined novel means the movement of whichis-governed-bythe total thickness of theyam layers applied to theyarnfreceivin'g device.

A further object is to provide such a machine comprisinga rotary yarnreceiving device and a reciprocally operatedvariable stroke yarn feedingelement which is automatically maintained in contacting relationshipwith theyarn receiving surfaceiof the device during the entire yarnwind- 5 5 on Fig. 6. 1

when the said device is temporarily disconnected from its driving meansas a result of yarn breakge. .j Y

Another object is to provide such a machine in which a movablemountingfora rotarryarn receiving deviceis uniquel associated-with tiltabletrack means to control the stroke of the yarn feeding element.

The usual and well-known parts of each individual yarn windingandtwisting machine unit closure of its construction and operation. Thispatented stop motion mechanism operates when The spring is is tentheyarn Y'breaksor runs out, and the yarn guide functions as'a detectorelement in this combination. when the yarn Y breaks or runs-out.

the guide 20 and certain associated parts (not shown) eflect release ofthe bar I4 for movement to the left in Fig. 6, so that the spring}! nolongerexerts a rearwardpull on the frame ll.

'I-he frame and the roll II are then free to move forward (to the leftin Fig, 6) under the influence of spring 30, thus breaking the drivingcontactbetween the'roll l1 and the drum l8.

' gRotation of the roll I! thereupon promptly ceases.

' the take-up roll'or cylinde cooperatively combined with the previouslyde scribed elements and mechanisms are novel means for controlling thestroke of the yarn feed element 22 t6 eflect win g 'of the yarn Y on IIin such manner that the yarn and cylinder will form a so-calledfheadless" yarn package having tapered or inclined ends. Suchmeansgenerally comprise a track member 36, a carriage 37,.a connecting rod 38the upper end of which is provided with a ball 39 arranged to form 'auniversal joint with an adjustable socket devicej40 secured to trackLand 20 over a fixed guide member :1 through a yarnguide or feedingelement 22, to the surface of thetake-up roll ,ll.

Since the element 22. will at alltimes be posi-v tioned to the right (Figs. 6 and 11) of the pivot pin54, during a particular yarn widing opera- 'tion or clycle, contact ofthe element 22 with the vided with the usual complement of such unitsconnection between the take-up roll I] and drum 7 It, so that rotationof the roll I! ceases.

t will be notedthat during the winding joperatlon, the yarn feed element22 is continuously" in direct contact'zwith the surface to which .theyarn is applied, and that the yarn is consequently guided to its exactpoint'of application at all times. This feature, in conjunction with themeans for progressively varying the stroke of the yarn feed element indirect correspondence with the total thickness, ordiameten-of the yarnts, it will be understood that the r machine or apparatus of myinvention is proeach embodyingthe elements and mechanisms previouslydescribed.

. The operation of each such individual unit When starting a yarnpackage, the end of the yarn is wrapped around a fresh or empty I rollH, in usual manner," and the latterf'is then mounted in its bearingelements 25 at the'upper end of the swinging frame 25. The bar "is thenmoved rearward by manual pressure on the knob until the spring 33 isunder'the tension. required to place the take-up roll "in drivingcontact with the druml8. and the previously referred tc stop motionmechanism" 'is'set for operation in accordance withthe disclosure of mysaid Patent No; 2,258,914.

Reciprocation of the carriage 31 by the traversing rod23 effects movement of .the roller 48 along the track or runway 41, backand forth, thereby correspondingly'moving the yarn feed element 22 atthe upper end' of the plate 53 which means connecting said movablemounting and .is pivotally connected with thecarriage 81. As-

the angle of tilt, of the track "increases, the stroke of the yarn feedelement 22 decreases.

This will become. more apparent by reference to yam feed element22 at.the extreme ends of their stroke to the right and left. atthe .time
